Abstract

A variable geometric light source and related method for illumination comprises a dense array of micro light emitting diodes (LED) incorporated within a printed circuit board and controlled by an incorporated microcontroller. The microcontroller receives user input and causes the dense array to illuminate according to the input. A tunable lens operates to focus the LED illumination toward one or more specific target subjects to creat a variable geometric light projection. The microcontroller is configured with instructions which cause the dense array to produce a variety of shapes, intensities, and color temperatures tailored to the individual installation. The microcontroller causes the dense array to create a light projection suitable for illumination of a subject as well as a dynamic projection animated for a communication to the viewer.

Description

Background technique [0001] Personal lighting can present a number of challenges when installed within an overhead compartment of a personal space. Personal lighting devices may provide an individual with a light source for illuminating a subject of interest. For example, passengers on an airplane or ground-based vehicle may desire to illuminate a book or map, while an engineer in a laboratory may desire controllable illumination of a circuit board. Additionally, a medical professional may desire controllable lighting of specific points on a subject of interest. [0002] A light source may generate heat, requiring additional functions of the light source to ensure fire compliance and to remove the heat safely. In the aircraft example, heat buildup in the overhead compartment may cause additional problems for the aircraft operator. [0003] A controllability feature that users may expect not found in current light sources. For example, the dentist must physically touch her ...
